A very relevant and purposeful G1 centric thread

This thread is not for use to disparage other TF continuities. Though I am partial to G1 as there are many questions that are running in my head that there are times I want to know why? Let's just focus on the G1 cartoon continuity (lets include the Japanese take post Season 3 if you like).
Since I know at least two people here hard wired into Vector Sigma's database I am raising a question about a retcon time travel issue in the Japanese coninuity.
I hope anyone can at least help to get it straight because it's bugging the heck of me.
In Car Robots, it got retconned into G1. Brave Max was buried into the earth's core to guard over Unicron's essence.
Later we learn, through KISS Players the Primus was responsible for this. But I need to clarify something:
1. In the past, Primus created Brave Max and left him to guard Unicron
2. Until RID, Brave Max left his post to got to imprison Destronger Megatron
3. Brave Max returns in Robotmasters to be part of Autobot City
4. WTF? The Autobots just received a city sized TF out of nowhere and just incorporated a Divinely designed transformable fortress at face value and incorporated him into Autobot City?
5. During the Battle for Autobot City in 2005, Brave Max just remained inert? WTF?
6. Post KissPlayers when TFs were welcomed back by the EDC, Brave Max was used as a concert venue of sorts until the Sparkabots deceived the KissPlayers to search for Unicron's essence.
7. BraveMax hit a wall in the time stream and crashed to Planet Master where the future Headmasters led by Fortress reversed engineered Brave Max into their super science.
8. WTF? Optimus and their crew already had in hand Brave Max and didn't reverse engineer the technology back before 2005?
9. At what point in the modern era did Metalhawk and the Pretenders pursue the 'cons back into Earth's neolithic age? Was it after the Japanese Headmasters or earlier? Grand Maximus was with them in Pretenders form, and he IS Fortress' bro right? So when DID the Pretender technology start to be used?
10.After defeating the 'cons, so Metalhawk and crew, from the future, stayed on the Earth since the neolithic time on wards to the present just hiding? So as not to disrupt the space time continuum?
